Russian drones are increasingly appearing over German military bases and the routes of arms transports to Ukraine. The media report systematic espionage. Germany is said to be inadequately prepared for the resulting dangers. In an interview with ZDFheute live, security and intelligence expert Hans-Jakob Schindler explains how Russia operates and what weaknesses German authorities have. Russia's espionage is about assessing and gradually destroying the fighting power of its opponents. The aim is "also to undermine cohesion within an opposing society, in this case Germany". To achieve this, Moscow relies on "misinformation and disinformation, propaganda, but also by spreading fear", explains Schindler.
